Re: first time out with eco9
Yes, but in actuality you would wish that it didn't. There is a general misunderstanding about cans, that being that like a barrel or receiver, you want it clean. You don't, just the opposit. You want as much filth to collect in the can as you can with one exception, filth that cannot be purged out of the can. Lead is a problem in rimfire cans because the bullets are unplated. It cakes and causes true hardship within the can. That is why we do not shoot rim fire through our centerfire cans. If we absolutely must, we use copper coated rimfire rounds as that cuts the leading way, way back. Aside from that, we never clean our can in the traditional sense of the word (more on this later.) Rather, we want to increase the internal turbulance and increase the deadening effect on frequency of debris held temporarily in the can itself.
Again, so there is no confusion, what follows is for PISTOL cartridge suppressors. Rifle cans are not typically run wet and can be dangerous as the higher pressures can cause hydrolock, a dangerous condition. PISTOL cartridges do not have this issue. This is where one should always say "check with our manufacturer as to whether your suppressor can be run wet."
There are a number of ways we do this:
1. We never clean a centerfire can until the can becomes perceptably louder. That takes thousand and thousands of rounds. Long before that, it will take thousands of rounds to QUIET your can DOWN. Building up simple propellant debris will soften the noise considerably.
2. We add wetting agents (ablatives) to "wet cans" to increase turbulance as well. This, along with the cooling capabilities makes a huge difference in performance. A can with lithium grease will be quieter, run cooler, have far more turbulance. It will smell for a good number of rounds as well and, if not loaded with the right amount (10cc) from the right end (thread) and the right way (side injected into the cavities while twisting for the first 1/3rd), they can spit. Do it properly and they do not.
3. White lithium grease protects all the internals of your can:
- Better corrossion protection
- Better lubrication of the Neilson in some designs
- Keeps the crap in suspension while increasing turbulance
- Suspended crap is "purged" out of the front of the can with a majority of good designs.
4. It all comes out:
- Either through heat and gassification/liquification
- or by using a cleaning tool (RARELY!, like every 4,000/5,000 rounds).
- That tool has a simular apprearence to the loading tool. Side mounted jets that spray high pressure water into the can and get all the particulate out. Will it remove lead? No, there should not be a leading problem. When the can sounds louder, it is because some designs are "capture designs" that have ports going to the outside of the armature, but that debris gets caught inside the envelope without anywhere to go. Most of those designs MUST be able to be opened up. If not, this tool can help them too. I should note that most folks DO NOT want to take out ALL the crap in their cans. You can clean the particulate in your can all the way back with this tool only to find you will have to shoot it back up with crap to quiet it.
In other words, grease is always quieter with zero downside in most designs.
The cleaning tool:
Watch this is you want to get a full dose...

Good luck.
